The grid-forming wind turbine generator (GFM-WTGs) using inertial synchronization control (ISynC) has a good support function on grid frequency and voltage, but its low voltage ride through (LVRT) strategy will challenge the heat dissipation of the unit and is now less researched. In addition, when adjusting the frequency, there is also the problem of reserve power waste and insufficient adjustment margin. In view of the above problems, the joint control strategy of wind and storage with ISynC plus DC side energy storage is proposed to ensure the power balance during the LVRT and avoid energy waste during frequency regulation, and finally the feasibility of the control method and the correctness of the theory are verified based on the PSCAD/EMTDC simulation platform.
